Hello,
I gave variables like this:

Array

Which means:
0. Not using
1. Pill
2. IUD
3. Injections 3 month
4. Male condom
5. Female sterilization
6. Male sterilization
7. Periodic abstinence
8. Withdrawal
9. Other traditional
10. Implants/Norplant
11. Lactational amenorrhea (LAM)
12. Other modern methods
13. Injection 1 month
I want to calculate the score; for example, the score is 1 if using a pill, 2 if using female sterilization, 3 if using other modern methods, etc. Then I want to determine the cut-off-point using ROC. How should I write a command in Stata? Hopefully, someone can help me
